A business name registration is valid for five years, after which time it must be renewed. It is your responsibility to keep information on the registration up to date and you are responsible for renewing your registration before the end of five years. A change to a business name or business type (e.g. general partnership to a sole proprietorship) is considered a new registration and you are required to pay the registration fee.
Upon registration you will receive a Master Business Licence commonly referred to as the MBL. The MBL can be used as proof of business name registration at financial institutions and to facilitate other business-related transactions with the Ontario government.
Business names are registered with the Companies and Personal Property Security Branch (CPPSB) of the Ministry of Government and Consumer Services (MGCS) and are placed on the Public Record maintained by CPPSB for public disclosure. Anyone may search business name information contained on the Public Record for a fee to find the owners or principals behind a business name.
Who must register under the Business Names Act?
The Ontario Business Names Act administered by the Companies and Personal Property Security Branch applies to:
- sole proprietorships (one owner) carrying on business under a name other than the individual’s full name;
- partnerships carrying on business under a firm name other than the full names of the partners;
- corporations carrying on business under a name other than their corporate name;
- an existing general partnership or limited partnership registering a business name different from the registered firm name;
- limited liability partnerships;
- extra-provincial limited liability partnerships; and
